I’m embedding the Flowable process engine in my stack and want BPMN.io to drive the workflow layer of our mobile app. To make that possible, I need a specialist who can create and wire custom connectors—no forms or scripts, just robust connector logic—so the processes we model in the browser execute seamlessly on-device. Here’s what I’m looking for: • Analyse the existing mobile architecture and the way Flowable is currently embedded. • Design, code, and register custom connectors (Java/Spring or equivalent) that call our external services, map the responses, and return clean payloads back to the engine. • Extend the BPMN.io modeler palette so these connectors show up with proper icons, names, and property panels. • Ensure deployed workflows run flawlessly inside the embedded Flowable engine, tested on both Android and iOS builds. • Deliver unit tests, inline documentation, and a concise hand-off guide so my team can maintain and extend the solution. Acceptance criteria: 1. Custom connectors appear in BPMN.io and deploy to Flowable without manual XML tweaks. 2. An end-to-end demo proves a sample mobile process exchanges data through the connector and reaches completion. 3. Source code is clean, well-commented, and ready for CI/CD integration. I need this completed ASAP, so only bid if you can jump in immediately and have prior experience with Flowable, bpmn-js, custom element templates, and mobile-backed APIs. Let’s get these workflows live fast.
